Cut 2.0 x 1.5 breadboard lengthwise such that one piece had the center screw holes intact.  

P1 is pressure side of pressure sensors.  P1 is port closest to Pin 4.  Pin 1 is the notched pin.  Solder pressure sensors to breadboard such that the P1 ports are towards the back of the enclosure so that the tubing has the greatest bend radius available.  This will mean that the sensors are soldered with pin one facing the front of the enclosure (front being the side with the pitot probe)

Probe.ino has Pitot Pressure (Pfwd) voltage on Pin A2 and Angled Probe Pressure (P45) voltage on pin A3.

Pressure Sensors current draw is 6 mAdc at 3v.  The Feather board voltage regulator can produce an excess 250mA after powering the ESP chip, enabling the Feather board to supply the 12 mA for the pressure sensors.

This leaves us with the following connections.

• Feather
  • Gnd - Pfwd and P45 pin 1
  • 3v - Pfwd and P45 pin 3
  • A2 - Pfwd Pin 2
  • A3 - P45 Pin 2
• Pfwd
  • P1 connected to Pitot Tube barb with 4mm ID tubing
  • P2 left open to inside of enclosure
  • Pin 1,2,3 see above
  • Pin 4 - NC
• P45
  • P1 connected to Angled plenum barb with 4mm ID tubing
  • P2 left open to inside of enclosure
  • Pin 1,2,3 see above
  • Pin 4 - NC

• Solder headers to OLED Wing.  Do not solder Wing to Feather yet
• Make connections from NeoPixel Strip and Gas Sensor to OLED Wing
  • Wing to Feather
    • GND and 3V
    • SCL and SDA to connect I2C bus  
    • Buttons: 
      • Button A - A8 
      • Button B - A7 
      • Button C - A6
  • NeoPixel to Wing/Feather (note: solder to inside row of holes on the Wing)
    • Gnd - Gnd
    • Power - VBat
    • Data - A5
  • Gas Sensor to WIng/Feather (note: solder to inside row of holes on the Wing)
    • Gnd - Gnd
    • Vin to Feather 3V or Bat (if using BME633 breakout board)
    • SCK to Wing SCL
    • SDI to Wing SDA
• Screw NeoPixel Strip, OLED Wing and Gas Sensor to enclosure
  • Test OLED Wing Buttons with Enclosure buttons.  Ensure that they are not pre-depressed or cannot be engaged.  Will not be able to make adjustments easily after the Feather is soldered to the WIng as the screws will be difficult to reach.  Longer screws may also be used if available, in which case you can solder the Feather to the Wing prior to screwing to the enclosure
• Place Feather on OLED Wing (which has been attached to enclosure) and solder.
